Boeing 777-9 Vibration Testing Advances 2026 Certification Plans
Boeing conducts ground vibration testing on the 777-9, moving closer to 2026 certification and 2027 delivery to Lufthansa.
This article is based on an official update from Boeing and additional industry data regarding the 777X program.
Boeing 777-9 Undergoes Critical Vibration Testing Ahead of Production Flight
Boeing has initiated a significant phase of ground testing for its flagship 777X program, marking a pivotal step toward certification. According to an official update titled “Shaking it up: Boeing conducts 777-9 vibration testing,” the manufacturer is currently performing vibration assessments on the airframe. This milestone comes as the program accelerates toward the maiden flight of the first production-standard aircraft, tentatively scheduled for April 2026.
The testing represents a crucial transition for the delayed widebody program. After overcoming technical hurdles in 2024 and 2025, including specific structural redesigns, Boeing is now focused on validating the final configuration of the jet. Industry data indicates that this specific testing regime is a mandatory prerequisite for the Federal Aviation Administration (FAA) to grant Type Inspection Authorization (TIA), which clears the way for certification flight testing.
Understanding Ground Vibration Testing (GVT)
While the company update refers playfully to “shaking it up,” the engineering reality is a rigorous safety process known as Ground Vibration Testing (GVT). During this procedure, the aircraft is typically suspended or supported on soft cushions to isolate it from the ground. Engineers then use electro-dynamic exciters, or “shakers,” to vibrate the airframe at specific frequencies.
The primary goal of GVT is to measure how the aircraft structure responds to these vibrations and to verify that the physical aircraft matches the theoretical aeroelastic models used during design. This ensures the aircraft is safe from “flutter”, a dangerous phenomenon where aerodynamic forces and structural vibrations reinforce each other, potentially causing structural failure.
Why This Test Matters Now
According to program reports, this round of testing is likely being conducted on the first production-standard 777-9 (identified in industry logs as WH005). Unlike previous test aircraft, which were pre-production models, this airframe features the final, certifiable design. The FAA requires GVT on the final configuration to ensure that recent changes, specifically the redesign of the thrust links, have not introduced new resonance issues.
Program Recovery and 2026 Milestones
The 777X program is currently navigating a critical recovery period following a six-to-seven-year schedule slide. In mid-2024, the test fleet was grounded after a thrust link, a titanium component securing the engine to the wing, cracked due to unexpected vibrations. Boeing redesigned the component and resumed flight testing in January 2025.
Since the resumption of flights, the program has hit several key targets in early 2026:
- Simulator Qualification: On February 19, 2026, regulators granted interim qualification for 777-9 flight training simulators, allowing pilot training protocols to be finalized.
- Icing Trials: In February 2026, engineers conducted “designer ice” testing, attaching 3D-printed ice shapes to the airframe to validate flight characteristics in freezing conditions.
- Brake Testing: Certification testing for the “autobrake” system also commenced in February, evaluating the aircraft’s automated stopping capabilities.
Updated Timeline for Entry Into Service
With the thrust link issue resolved and vibration testing underway, Boeing has updated its delivery targets. The manufacturer now expects certification in the second half of 2026. Consequently, the first commercial delivery to launch customer Lufthansa is targeted for 2027.
“2026 is a year of certification, certification, certification.”

AirPro News Analysis
The commencement of Ground Vibration Testing on a production-standard airframe is a strong signal that the 777X design is frozen and stable. For years, the program has been stuck in a loop of discovering defects and engineering fixes. This “shakedown” suggests the conversation has finally shifted from troubleshooting to validation.
However, the timeline remains tight. With an April 2026 target for the production aircraft’s first flight and a certification deadline later this year, there is little margin for error. The FAA’s methodical approach to Type Inspection Authorization means every test point will be scrutinized more heavily than in previous programs. While the “shaking” is happening on the ground today, the real test will be maintaining this momentum through the regulatory hurdles of late 2026.

Boeing and Icelease Agree on Up to Three 767-300BCF Aircraft
Icelease signs for up to three Boeing 767-300BCF aircraft, with conversions at ST Engineering Singapore starting Q1 2027.
The Boeing Company and aircraft lessor Icelease have finalized an agreement for up to three Boeing 767-300 Boeing Converted Freighter (BCF) aircraft, marking the leasing firm’s expansion into the medium widebody cargo market.
Announced in a press release on November 2, 2026, the transaction includes one firm order and options for two additional conversions. The aircraft will join the managed cargo portfolio of IAT Leasing, a Dublin-based sister company to Icelease.
Conversion timeline and operational details
The formal signing ceremony for the agreement took place on October 22, 2026, during the Cargo Facts Symposium. The physical conversion work will be executed at ST Engineering’s airframe maintenance, repair, and overhaul (MRO) facilities located in Singapore.
Induction of the first Boeing 767-300 aircraft for conversion is scheduled for the first quarter of 2027. Delivery of the completed Boeing 767-300BCF to Icelease and IAT Leasing is expected to follow in the second quarter of 2027. The Boeing Converted Freighter programs are managed by The Boeing Company’s Global Services division.
Lindsey Douglas, Vice President of Cabin, Modifications, Maintenance and Digital Services at The Boeing Company, stated that the agreement underlines the continued collaboration between the two companies to meet global cargo demand.
Sigthor Einarsson, Managing Partner at Icelease, noted the strategic importance of the deal for the lessor’s broader fleet strategy.
“This agreement with Boeing to convert up to three Boeing 767 aircraft marks an important milestone for both Icelease and its Dublin-based sister company IAT Leasing,” Einarsson said.
Icelease and IAT Leasing’s growing cargo portfolio
The Boeing 767-300BCF order builds upon an established relationship between the manufacturer and the lessor. Icelease, an aircraft leasing company with a 21-year history, specializes in aircraft acquisitions, leasing, operations, finance, and investor relations. The firm was originally formed as a spinoff from Icelandair in 2005.
On November 14, 2021, Icelease placed an order for 11 Boeing 737-800 Boeing Converted Freighter (737-800BCF) aircraft during the Dubai Airshow. That order established Icelease as the launch customer for a new conversion line at Boeing’s London Gatwick MRO facility.
The newly ordered widebody freighters will be managed by IAT Leasing. Incorporated in late 2023, IAT Leasing is owned by four equity partners. The Dublin-based entity has rapidly built a portfolio of approximately 40 narrowbody and widebody passenger and Cargo aircraft, which are leased to operators globally. The company’s current managed cargo portfolio already includes seven Boeing 737-800BCF aircraft.
“The history between Icelease and Boeing dates over 20 years and includes a multitude of new aircraft deliveries as well as cargo conversions,” Einarsson said. “The Boeing 767-300BCF will join the growing managed cargo aircraft portfolio of IAT Leasing, which already includes seven Boeing 737-800BCF and other freighters leased to various customers.”
Widebody freighter market outlook
The Boeing 767-300BCF is positioned to serve regional and long-haul cargo networks as a highly efficient medium widebody converted freighter. The aircraft offers a payload capacity of 57 tonnes and a maximum range of 3,300 nautical miles.
The Icelease order aligns with broader industry forecasts regarding long-term air cargo growth. On October 28, 2026, The Boeing Company released projections indicating that the global freighter fleet will exceed 4,000 airplanes by 2045. The manufacturer anticipates that air cargo traffic will double over the same period, providing a sustained demand environment for passenger-to-freighter conversion programs across both narrowbody and widebody platforms.
AirPro News analysis
We view Icelease’s transition from narrowbody to medium widebody conversions as a natural progression for lessors seeking to capture higher-yield cargo segments. While the Boeing 737-800BCF serves domestic and regional express networks effectively, the Boeing 767-300BCF provides the volume and range necessary for intercontinental e-commerce flows. By securing conversion slots at ST Engineering for 2027, Icelease and IAT Leasing are positioning their portfolio to absorb capacity demands as older widebody freighters face retirement toward the end of the decade. The decision to allocate these assets to the recently formed IAT Leasing also highlights the robust investor appetite for dedicated freighter leasing vehicles.

AerCap Leases Two Boeing 777-300ERSF to Turkish Airlines
AerCap finalizes lease of two Boeing 777-300ERSF freighters to Turkish Airlines, with deliveries scheduled for 2027.
AerCap Holdings N.V. has finalized lease agreements with Turkish Airlines for two Boeing 777-300ERSF converted freighters, with deliveries scheduled between March and September 2027.
Announced on October 29, 2026, the transaction expands the Turkish flag carrier’s dedicated cargo capacity while utilizing Etihad Engineering’s maintenance, repair, and overhaul (MRO) facility in Abu Dhabi for the passenger-to-freighter (P2F) modifications. In a press release detailing the agreement, the Dublin-based aviation lessor emphasized the strategic alignment between the aircraft’s capabilities and the airline’s expanding freight network.
Expanding Turkish Airlines’ cargo operations
The agreement builds on an existing relationship between AerCap and Turkish Airlines, which operates a large international network requiring substantial dedicated cargo lift. The addition of the two widebody freighters is intended to support the carrier’s volume requirements on high-demand international routes.
Peter Anderson, Chief Commercial Officer at AerCap, stated that the aircraft will provide the airline with additional cargo capacity combined with the performance capabilities specific to the 777-300ERSF platform. Financial terms of the lease agreements, including the exact lease duration and the specific aircraft serial numbers, were not disclosed in the announcement.
The Big Twin conversion program
The Boeing 777-300ERSF, marketed as “The Big Twin,” is a P2F conversion program developed through a joint venture between AerCap and Israel Aerospace Industries (IAI). It represents the first program designed to convert the Boeing 777-300ER into a dedicated freighter configuration.
According to AerCap’s cargo division, the 777-300ERSF offers 25 percent more cargo volume than the factory-built Boeing 777-200LRF. This increased capacity positions the converted twin-engine aircraft as a cost-effective replacement for aging four-engine Boeing 747 freighters currently operating in the global fleet.
AerCap delivered the first 777-300ERSF to launch customer Kalitta Air in September 2025. Since that initial delivery, the lessor has handed over aircraft to Fly Meta and secured lease agreements with other major operators, including Ethiopian Airlines and China Southern Group.
Regional conversion strategy in Abu Dhabi
The physical conversion of the two aircraft destined for Turkish Airlines will be executed at the Etihad Engineering MRO hub in Abu Dhabi, United Arab Emirates. This facility serves as a dedicated regional conversion center for the 777-300ERSF program.
Anderson highlighted the strategic importance of the location, noting that the Abu Dhabi facility provides a regional platform capability that enables aircraft to be converted in the Middle East prior to delivery. This localized approach is designed to efficiently serve customers across the Europe, Middle East, and Africa (EMEA) market.
“The dedicated 777-300ERSF conversion facility at Etihad Engineering’s MRO hub in Abu Dhabi provides an important regional platform capability, enabling the aircraft to be converted in the Middle East ahead of delivery to Turkish Airlines,” Anderson said.
AerCap’s broader market position
The Turkish Airlines agreement follows a period of strong financial performance for AerCap. On October 28, 2026, the company reported its third-quarter financial results, citing record adjusted earnings per share and raising its full-year 2026 guidance amid high lease rates and sustained demand for aviation assets.
As of September 30, 2026, AerCap’s total portfolio included 1,537 owned and managed aircraft, alongside approximately 1,300 engines and over 300 helicopters. The company’s dedicated cargo division manages a fleet of approximately 110 owned, managed, and on-order freighters, having completed more than 160 passenger-to-freighter conversions to date.
AirPro News analysis
We view the placement of 777-300ERSF aircraft with a major network carrier like Turkish Airlines as a strong validation of the Big Twin program’s economic proposition. As operators look to phase out older Boeing 747 freighters, the 25 percent volume advantage over the 777-200LRF makes the converted 300ER an attractive middle ground between factory-built twin-engine freighters and legacy four-engine platforms. Utilizing the Etihad Engineering facility in Abu Dhabi for a European customer also demonstrates the logistical efficiency of AerCap’s decentralized conversion strategy, reducing ferry times and regional friction for EMEA operators.
